Gillingham manager Martin Allen saluted his team after they made history by setting a new club record with an 11th away win.
Cody McDonald's second half header was enough to secure the points against Chesterfield and keep Gillingham at the top of League Two.
"It's a fantastic performance all-round from the squad," Allen said. "The great thing is there are so many players who can go in and play.
"We defend as a team and we attack as a team. We played one or two touch football, moved the ball about and though it was a bit scary in the last 20 minutes, we've seen it a million times. When we defend in numbers we are strong and we are not left open.
"It's a victory for the club and it's an historical day to be honest for the club, the players, supporters, chairman and to be manager and get this record makes me very proud.
"Breaking a record of 100 years is fantastic. Deon Burton came in at the end and said 'well done lads, we've made history' and that's all we spoke about. To be the squad and part of the club when we made history is quite amazing."
